The present research focuses on the development of environmental friendly packaging materials based on biopolymers such as polyesters, i.e. (PLA), polysaccharides (cellulose, chitosan and gum) and their structural complexes modified to a larger extent, to fulfil the requirements of the sustainable future. In order to meet the current demands of the industry and consumer needs, the addition of PLA with nano-functional biofiller is found to be a compelling alternative to the conventional plastic packaging. Nano-functional biofillers are considered to be most suitable alternatives to develop green biocomposites when incorporated into the PLA matrix which offer the advantages of biodegradability, renewability along with balanced properties. The melt processing of PLA with biofiller is a challenging task as the material undergoes thermal decomposition at elevated temperature and the shearing action results in the reduced melt strength. The modification of biofiller is one such strategy which may be adopted to overcome these limitations.enCHEMICAL ENGINEERINGThesis
